Step 1) Find out how much of the circle we need to find the area of
In the missing piece of the circle, we can see a right angle, or 90 degrees. Let's find the fraction of the circle that is remaining.
360 - 90 = 270
Remaining fraction: 270/360 = 3/4
Step 2) Find the area of the whole circle
A = pi x r^2
A = pi x 4^2
A = 16pi
Step 3) Use the fraction we found in step 1 and multiply that fraction by the area of the whole circle
16pi x 3/4 = 12pi
A = 12pi = 37.68 units^2
Hope this helps! :)
First we need to find the equation of line .
Here the line passing through (0,-1) and (-1,1). So the y intercept is -1 here.
Now we need to find the slope , m.
So we have slope, m =-2 and y intercept , b=-1
And the slope intercept form is y=mx+b.
Substituting the values of m and b,
y=-2x -1
Here point (0,0) is a part of the shaded region.
It means point (0,0) must satisfy the inequality.
Let's plug point (0,0) in the equation
0=-1 and 0 is greater then -1. So the inequality have to be
y>-2x-1 .
Greatest common factor (GCF) of 7 and 15 is 1. We will now calculate the prime factors of 7 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 15.
It will be able to be cut into 30 sections.
3 meters = 300 centimeters. 300 centimeters divided by the length of each section, 10 centimeters which equals 30 sections.
